MPEG视频小组目前正在开发所谓的MPEG-4视频编码标准，其目标是未来交互式多媒体视频通信，要求基于内容的功能、在容易出错的环境中的通用访问以及高编码效率。除了基于内容的功能之外，MPEG-4 视频标准还将有助于在容易出错的环境中有效存储和传输极低比特率视频。本文概述了 MPEG-4 目前正在研究的技术，旨在以极低的比特率提供视频的通用可访问性，并讨论了一些正在讨论的有前途的技术的范围。
The MPEG video group is currently developing the so-called MPEG-4 video coding standard, targeted for future interactive multimedia video communications calling for content-based functionalities, universal access in error prone environments and high coding efficiency. Besides the provisions for content-based functionalities the MPEG-4 video standard will assist the efficient storage and transmission of very low bit rate video in error prone environments. This paper outlines the techniques that are currently being investigated by MPEG-4 to provide universal accessibility of video at very low bit rates and discusses the scope of some of the promising techniques under discussion.
